The object of the present invention is to provide a new and improved carbureter arranged to prevent frost from forming on the inside of the evaporating-coil or in the gasmains leading from the apparatus and to permit of recharging the storage-tank without any danger.

The invention consists of novel features and parts and combinations of the same, as will be fully described hereinafter and then pointed out in the claims.

A practical embodiment of my invention is represented in the accompanying drawings, forming a part of this specification, in which similar characters of responding parts in all the views.

and actuated wire, or cable A leads from the lower end of the coil G into a drip-pipe G e that has not coil G to flow into the drip-pan G from which the accumulated gasolene is pumped from time to time back into the gasolene-storage tank A, as hereinafter more fully described, without, however, subjecting the gasolene to the acduring the transfer from the drip-pan G to the tank A.

As shown in the drawings, the drip-pan G the tank E, the chamber B, and the storageother, so as to reduce the size of the apparatus as much as H discharges into a pipe J,

opening into and the gas accumulating in said bell K is passed into the the gas to the The evaporating-pan D is provided with transversely-extending partitions or ridges D, rising a suitable distance from the bottom, but terminating below the top as is plainly indicated in Fig. 1. The partitions are arranged in such a manneras to gasolene flowof the pan,

d thereof (see the lower end the evaporating-coil G, as previously described, the air, however, passing over the partitions upon the gasolene as the passed through the latter slowly flows from the upper end of the pan toward the lower end thereof.

In order to distribute the air entering the pan through the pipe F, I provide a transversely extending perforated partition D next to the entrance end of the pipe F, so that the air is divided and spread over the entire pan D to come in contact with all the gasolene during the flow of the latter through the zigzag passage to cause a rapid evaporation of the gasolene and a consequent mixing with the air to form the gas.

It is evident that when the air-pump H is started a suction is caused in the coil G and pan D, and consequently the air readily passes from the pipe Fin and through the pan D and into the coil G, so that the gasolene that has not been evaporated completely in the pan will finally be evaporated and mixed with the air in the coil G previously to its passage into the air-pump H by way of the pipe G. Any liquid not evaporated passes through the drip pipe G into the drip-pan G as previously explained. v

The pipe F, as shown in Fig. 1, extends upwardly and contains a valve F, controlled from the gasolneter-bell K, simultaneously with the lever O for opening the valve 0, controlling the outflow oi the gasolene from the chamber B into the evaporating-pan D. On the top of the pipe F is arranged a cap F which is removed during the warm season to allow atmospheric air to be drawn through the pipe F into the pan D by the action of the pump H for forming gas, as above described; but during the cold season the cap F is placed in position on the pipe F to close the same, and then the air for forming the gas and pipe F is previously heated. For this purpose the pipe F and the cap F are connected by a branch pipe F with a warmer F in the form of a closed tube, through which passes the gas-main K after leaving the gasometer-tank K. The warmer F is connected by a pipe F with the top of a heating-drum L, arranged alongside the wator-tank E, and having a burner L of any approved construction in the lower open end of the shell for the heater L. The burner L receives its supply of gas from a pipe L connected with the outlet-pipe J for the pump H. A valve L in the pipe L serves to control the amount of gas passing to the burner. Inside of the shell for the heaterL is arranged a heating-core L preferably made hollow and surrounded by acoil E, connected at its lower and upper ends by pipes E E with the bot tom and top portions of the water-tank E.

"When the apparatus is in use during the winter time, the heat from the burner L heats the water circulating through the coil E, so that the water in the tank E is always at a proper temperature to insure a proper heating of the coil G and the evaporatingpan D for producing the gas without danger of frost forming in the said evaporating-pan and the said coil.

The air entering the shell of the heat-erL is likewise heated and is passed through the pipe F and into the warmer F to heat the gas-main K so as to prevent the same from freezing or from forming frost on the inside of the pipe, and then the heated air passes by way of the branch pipe F into the pipe F, past the valve F, to finally pass into the evaporating-pan D.

The mechanism for controlling the valves F and 0 simultaneously and quickly from the gasorneter-bell K is arranged as follows: A swinging balance N, in the form of a tube containing a liquid ora ball, is pivoted at the middle at N to a bracket supported from the top of the storage-tank A. On the ends of this balance are arranged down wardlyextending arms N 2 N adapted to engage opposite ends of a lever O, fulcruined at its middle on the bracket carrying the balance N. This lever O carries on one end a weight 0 and at its other end an adjustable arm 0 pivotally connected with a crank-arm F on the valve F, so that when the lever() swings downward by the arm N coming in contact with the said lever thenthe valve F is closed; but when the lever O is swung back to the position shown in Fig. 1 by the action of the arm N on the other end of said lever then the valve E is opened. The lever O is also provided between its fulcrum and the arm 0 with a bearing 0 for a rod P, carrying two nuts P and P for engaging the hearing at the top and bottom, the nuts being adjustably held on said rod P. The latter extends through a stuffing-box A on the top of the tank Adown through a pipe A to carry at its lower end a weight P adapted to engage the'free end of a lever C for opening the valve 0 and allowing the gasolene to flow.

from the supply-chamber B into the upper end of the evaporating-pan D. The valve C, by its own weight or that of a spring, is normally held to its seat and is only opened when the lever 0 receives a swinging motion by the arm N moving in contact with this end of the lever, so that the rod P is moved downward and with its lower end act-hates the lever 0.

The balance N normally stands in a horizontal position, as shown in Fig. 1-, but receives a swinging motion in either direction from the bell K of the gasometer, and for this purpose the balance N is provided near the end carrying the arm N with a bearing N engaged by a rod Q, carrying adjustable collars Q Q for engaging the said hearing at the bottom and top. The upper end of the rod Q is pivotally connected with a lever Q fulcru med on a bracket Qflcarried by the gasometer-tank K, and the free end of the lever Q extends between two adjustable collars K and K ona rod K secured to the top of the gasometer-bell K and fitted to slide in a bracket Kflcarried by the gasometer-tank K.

When the several parts are in the position shown in Fig. 1, the valves F and C are closed, and when the gas in the gasorneter-bell K is withdrawn by way of the gas-main K then the bell K sinks and imparts a downward swinging motion to the lever Q so that the collar Q finally comes in contact with the bearing N to swing the balance N in the direction of the arrow a and cause the arm N to impart a swinging motion to the lever O in the same direction, whereby the valves F and O are opened to admit both air and gasolene to the evaporatingpan D. The gas now generated is pumped by the pump H into the gasometer-bell K, and as the latter rises an upward swinging motion is given to the lever Q so that finally the collar Q comes in contact with the bottom of the bearing N and imparts a swinging motion to the balance N in the inverse direction of the arrow a, so that the arm N finally comes in contact with the left-hand end of the lever O to impart a swinging motion to this lever in the inverse direction of said arrow. When this takes place, the valve F is closed and the valve-lever O is released by the rod P to allow the valve 0 to close by its own weight or a spring connected with the valve for that purpose. The flow of the gasolene and air is thus shut 0E from the evaporating-pan D, and a further generation of gas ceases until the bell moves back to a lowermost position, as previously explained.

A supply-pipeR for supplying the gasolenestorage tank with gasolene is provided with a check-valve R and opens into a tank S, connected with a pump T, of any approved construction. The bottom of the tank S is provided with a suction-pipe S, having a suctionvalve S and said pipe S is connected with a pipe U, opening into the drip-pan G and having a valve U for connecting or disconnecting the drip-pan and the pipe S. A pipe V, having a valve V, also connects with the suction-pipe S, and this pipe V is adapted to be connected by a hose or other means with a shipping-tank for pumping the gasolene direct from said shipping-tank into the storagetank A. In order to do this, the valve U is closed and the valve V is opened, and then the pump T is set in operation to pump the gasolene from the shipping-tank by way of the hose, pipe S, tank S, and pipe B into the storage-tank A.

When it is desired to empty the drip-pan G the valve U is opened and the valve V is closed, and then the pump T is set in action to draw the gasolene from the drip-pan G into the tank S and to then force it through the pipe B into the storage-tank A. Thus by the arrangement described the gasolene is passed from the shipping-tank or from the drip-pan G into the storage-tank without coming in contact with the air, so that no dangerous explosive mixtures are formed.

\Vhen the storage-tank A is filled with gasolene, a valve F in a pipe F connecting the tank A with the pipe F, is opened to allow the escape of gas formed in the storage-tank by way of the pipe F and pipe F into the evaporating-pan D, so that no gas whatever is lost.
